No slang words that promote laziness, ie; “r”, “u”, “plz”, etc. will be tolerated. Decent grammar is expected, including proper usage of capital letters. Repeated violations will be grounds for suspension and/or permanent removal from the forums.
b) there are many non-native English speakers that use these forums too. They've made the effort to learn and speak English, so please don't complicate things for them by littering your posts with "txt" slang.
That said, welcome to GT Planet. Have a good look around, there's tonnes of info here, and enjoy yourself!
